Manufacturing method of biodegradable micro-beads by melt electrospray process

摘要

Disclosed is a method for manufacturing biodegradable microbeads by a melt electrospray process using an aliphatic polyester which is a biodegradable polymer. The method for manufacturing biodegradable microbeads of the present invention comprises steps of: forming a melt of the aliphatic polyester; electrospraying the melt to form aliphatic polyester particles; solidifying and accumulating the particles in a hydrophilic coagulating bath; and drying the integrated particles. The method for manufacturing biodegradable microbeads of the present invention has a simple manufacturing process, can reduce a manufacturing cost, and can manufacture microbeads in an environmentally friendly manner.
